Seomyeon is the major downtown area of Busan. Seomyeon is a HUGE entertainment district, about 1 or 2 square kilometers of high bar/restaurant/shop density. Perhaps the largest such entertainment area in Korea.

OK, here's how it works. You call and pay 130,000 wons and a 100% agashi comes to visit your place. An agashi (or agassi or aggassi) is a korean word that refers to an unmarried woman or a young "babe". In case you (and her!) may not accept to stay, another agashi will be sent over until both of you agree for an hour of "entertainment". View photo in original size (659x679 pixels).

A Korean NightClub. Contrarily to the western nightclubs, not much dancing is going on here. Rather, there are private rooms costing 300,000 wons per man per evening. The waiter will then introduce a woman until one accepts to remain. Then, the couple can go out to a nearby love motel. View photo in original size (714x908 pixels).
